People for the American Way

A U.S. political organization, self-described as progressive, formed in 1981 by Norman Lear, Barbara Jordan, Theodore Hesburgh, Andrew Heiskell "and a group of business, civic, religious, and civil rights leaders who were disturbed by the divisive rhetoric of newly politicized televangelists (i.e., politically active religious conservatives)." It is nonprofit, but organized under section 501(c)(4) of the Internal Revenue Code, which allows it to lobby but cannot accept tax-deductible contributions.

They are explicitly opposed to principles of religious conservatism being applied to government.
